Abstract:   We introduce a category of linear algebra data called IC-modules, with relations of the form d2=0, equivalent to the category of stratification-constructible mixed perverse sheaves for flag varieties. Our construction does not use derived categories or t-structures, and makes sense for a wide variety of stratified spaces including toric varieties, affine Grassmannians, and locally symmetric spaces.



Here are some directions to Northeastern University. Lake Hall can be best accessed from the entrance on the corner of Greenleaf Street and Leon Street.
